Cooker Hood and Gas Hob (mains) supply
 
Can I run power to my cooker hood and gas hob (for ignition) from the
same fused spur (assuming the combined load to be less than the maximum
for the fused spur)?

I'm thinking that the need to isolate the hood from the mains to replace
bulbs, clean the filters or deal with combustion of the actual hood is
not likely to interfere with my use of the hob.

TIA Richard

Yes, from the load side of the fuse in the FCU. The load of the ignition
sparker and the hood should be well within 3A, so you probably won't need to
fuse down separately.

Probably not. (You're expecting your hood to combust?)

I cant see any need to isolate the hood from the mains just to change the
filters . Nor for changing the lightbulb-just make sure the switch on the
hood is "off".

Nor can I but the installers will not connect the hood direct to the
ring main.

That's because it's what the regs say. Something along the lines of
each fixed appliance shall be served by a DP isolator. Also, as a
cooker hood is usually 3A, and a ring is 32A, there's not much chance
of the MCB blowing until the kitchens on fire.

Any appliance connected to the ring main needs to be protected by a fuse -
either in a plug or FCU.
It's common to connect cooker hoods to the lighting circuit where no
separate fuse is needed.

Appliances with motors have to have separate isolators,
so you can maintain them with no risk of motor starting.

So common in fact, that in all my years as an electrician I've never
seen one connected to a lighting circuit.
You still need an isolator though, and if the destructions say 3A fuse
max, a 6\10A MCB won't do, and technically invalidates the warranty.

That's electricians for you - no imagination. In many cases it's easier to
access a lighting circuit than the ring due to the position.

And just how would they know what fuse was fitted?

They're better of on the ring, when the bulb blows it doesn't take a
32A MCB out, it more than likely will on a 6A, or with any other minor
fault type condition.

I did say technically. Although if one of the manufacturers happened
to send an engineer out, then....
And yes, I know it's very unlikely but technically.

Well, given a lighting circuit has a few bulbs that will blow anyway, I
can't see the problem with one more.

It's only a suggestion if it makes the wiring easier, as it might in some
cases. Not enough to start WW3 over.

True.

I think I was justifying my own reasoning really, I'll stick to
putting them on the ring but a lighting cct is a perfectly acceptable
solution also.
There, WW3 avoided!
